The skirt-chasing broker fined $429 million by the NYSE for allegedly swindling clients lived a secret life his friends and lovers knew nothing about, a former pal told The Post.

Enrique Perusquia, 47, was hit with the record fine for allegedly using his client’s accounts to buy stocks in shaky firms, the NYSE panel said.

The Big Board probe found that the Latin lothario lost $100 million of his client’s money and allegedly received cash kickbacks.

“He led a split life,” a former friend said. “There was so much I didn’t know and still don’t know. People who knew him were shocked.”

Most of Perusquia’s wealthy victims were family friends – members of Mexico’s financial elite.

The source said he seemed to change after he and his third wife, Donna Bloomfield, moved to Zurich, Switzerland in 1991. His first marriage, to Mexican soap star Lourdes Monguia, ended in divorce, as did his second.

Perusquia moved to the Alpine nation to feed his passion for Formula 1 car racing. The source said “it was the whole reason why they moved to Switzerland.”
